CVE-2022-25789

Code execution via unchecked DWFX object lifetime

Published Apr 11, 2022 · Updated Aug 3, 2024

Use-after-free in Autodesk AutoCAD 2019 through 2022 allows remote attackers to execute code through a malicious DWF, 3DS, or DWFX file. During DWFX parsing, the application operates on an object without first validating that the object still exists. Exploitation requires the target to visit a malicious page or open a malicious file, and resulting code runs in the current process.
